Installed this card in my Early 2009 Mac Pro. A new 4TB USB 3 external drive works great, but gets improperly ejected when the computer goes to sleep?

I do have problem with this card when using USB 3.0 card reader with my CF cards, regardless Sandisk, Lexar, or Komputer Bay, it keep eject and mount as a loop. I am getting very frustrated now with this card.

Answer from the company: generally almost computers have auto sleep function, but KT4004 USB 3.0 Express Card do not have wake up function, each time when your PC goes to sleep, you need to unplug the hard drive and then plug it again to make it work, hope you could kindly understand

OS X ejects the external drives when the computer goes to sleep, and pops up a warning when you return. Other than this annoying popup message, nobody has reported any actual problems. It's an OS X issue, not the fault of the card.

Try going to "System Preferences" and select "Energy Saver". Uncheck the box that says "Put Hard Disks to Sleep When Possible". That seems like a great thing which will help you save power, but from my experience it just causes issues with external hard drives. Hope this fixes things for you.

I have the 2 port one in my Early 2008 macpro. Just plugged it into the PCI slot and left the power connection empty. Works great.

It works under Yosemite but read/write times are much slower than USB 2.0. MacPro 3,1.

I am trying to use it with a Mac Pro. I can make it work but there are issues. The mac won't recognize it at startup. I have to unhook it and reconnect after startup. It works fine then, if I just put the mac to sleep its fine at wake up.

I use this on a MacBook running OS X 10.9.5, and the drive sleeps according to Energy Saver settings and when the computer sleeps. No problems at all, the drive wakes up when requested and stays mounted. Not sure about Windows, never had good luck there.

i had a cf plugged in at the same time i had a sdhc in, then plugged in a sd micro and it dropped the sdhc and did not register either sdhc or micro sd until i unplugged one or the other. (the same went for when i plugged in a sony MS Duo Pro) however the cf card never dropped out. side point: speeds are nice, usb 3.0 transfer was faster than with a firewire transferring the exact same video file.

You have a MacBook Pro that has a built in Superdrive. Per Apple the new, external Superdrive will not work with an of the older, aka Built in Superdrive computers. If you have time to return it, I'd return it to Amazon for a credit.

On my imac does work perfect, I do backup games on it and it does the job. Just let you that the drive is noise, to me doesn't matter because I only turn it on when I am backing up some data, If you need the drive on all the time, You probable will not like the device. You could buy a quiet fan and replace, it is my recommendation, otherwise it is a very good burning drive.

I have a 2012 mac mini running OS 10.8.5 and the 2TB version of this and it works but it seems to go to sleep frequently telling me in the midst of working on something that I disconnected it improperly. That's been a frequent annoyance as it mens I have to start over or stop everything to wake it back up again and usually re-do what I was working on. I have not lost any data and it seems to work fine as a hard drive but I never have this problem with the Seagate HD.

I run Yosemite 10.10.2 and have not noticed any difference in boot times (my disk connects via Thunderbolt 1.0, not USB 3.0). It does take the drive several seconds to boot up and become available after it goes to sleep (which is very annoying). The drive is fairly quick to go to sleep after non-use and I regularly have to wait for it to become available again. But it did that with Mountain Lion and Mavericks, too. Despite having to wait for it to wake from sleep I am quite happy with the drive. Having 8TB of space with super-fast data transfer is a joy.

My system has no trouble with the card. The Amazon cable I purchased does not handle USB 3.0 speeds. I thought the card was bad until I plugged a drive directly into the card.

I did go ahead and purchase this item, and it does seem to work fine with OS 10.3.9. Not sure why it won't show up or shut down on others' computers. I do know that I can't use the U3 software of the disk, but I just wanted it for storing things while traveling....very simple usage. Perhaps try using it in another port? Are you using it in a port directly on the computer itself? Sometimes I run into problems with peripherals when I plug them into my hub.

My 4TB drive is used as a backup drive in a Mac Pro computer (I have four internal drives). The first drive was faulty but it was promptly replaced by Western Digital and the replacement now works without any problems.

Mac Pros tend to have problems with USB 3 devices. Suggest a good USB 3 expansion card like SIIG and an extension cord. Hubs seem to have lots of problems. Also repartition the drive as GUID and use HFS+ formatting.

ExFat is default. But i used Mac OS Extended (Journaled), because i won't remove it often. And this card is a short one, so i think it may not match other sd card slot.

I installed the 500 G into my 2008 MacBook Pro on 3/28/12. It's quiet, fast, and has been excellent. Zero problems. I use the MBP every day running the battery (replaced once) down to 6-15% watching a movie in the evening. AC during the day for full recharge. Does the HD run all the time? I really don't know. I can't hear it. I have four 500 G externals that are used for backups (but not often enough :-( ). They are WD devices and I've have no problems with them either. I like the 500 size over any T sizes for reasons of redundancy. I double info onto the 500s, i.e. two 500s for the same back-up, thus if one goes down, I have a dupe. More than you wanted to know.

I can't speak for Life Span on this particular drive since I only have it for a month. So far, the unit work beautifully on my macbook pro 17" 2009. To be honest with you, I don't use it differently from the stock HD. I unplug the power cord, fold and put in my bag without quitting apps or shutting down and it wake up just fine. I can't even advise any Do & Don't for you. I've heard people concerning sleep mode issue and so on... The reason I pulled for this SSD. I've worked as a graphic artist for the last 18 years on apple macintosh. I've seen many HDD failed over the years. We've upgraded all our 9 mac pros to SSD since 2010. We use our macs 24/7 for production and they're very reliable and fast compare to stock HDD. So far, one failed after 2 years. Base on these facts, I can't imagine going back to HDD again. Yes, It's not 100% just like an airplane and that's why you always backup your stuffs. Finally, SSD 2014 are much improve than 2010. The # won't lie and I would buy with confident. Thank you for asking and good luck on your search,
